FIELD OF THE INVENTION

The present application relates to tattoo machines, adapter devices, power supplies, power delivery technologies, modular technologies, connector technologies, and, more particularly, to an adapter device for a tattoo machine.

BACKGROUND

In today's society, tattooing has become increasingly popular and ubiquitous. As a result, businesses are increasingly devoting financial resources, training skilled tattoo artists, and developing tattoo-related technologies to meet not only the increased demand from tattoo clients, but also the increasing quality and sanitation requirements that have become associated with tattooing. One of the tools that tattoo artists utilize to make tattoos on the skin of a tattoo recipient is a tattoo machine. Such tattoo machines may include motors, power sources, various controls, and other features to facilitate the reciprocation of needles of needle cartridges coupled to the tattoo machines. The reciprocation action of the needle generated by the tattoo machine enables a tattoo artist to apply the tattoo ink to the skin of a tattoo recipient so that the tattoo may be created. Currently, tattoo machines come in all sorts of shapes, colors, sizes, and functionality. Additionally, tattoo machines may be fitted with various grips, accessories, and other components as well, which may facilitate customization of the tattoo machines. Nevertheless, currently existing tattoo machines and tattoo machine accessories still do not provide all of the functionality, ergonomics, and/or features desired by tattoo artists.

As a result, there remains room for substantial enhancements to existing tattoo machine technologies and accessories to meet tattoo artists' needs. While currently existing tattoo machines and accessories provide for various benefits, such technologies still come with various drawbacks. For example, currently existing tattoo machines and accessories are often bulky, unwieldy, and/or difficult to operate. Additionally, current tattoo machines are often fixed in configuration and contribute to tattoo artist fatigue. Furthermore, currently existing tattoo machines have limited options for providing power to the tattoo machines. Based on the foregoing, current tattoo machines and accessories may be improved and enhanced so as to provide for improved modularity, more optimal tattoo machine and accessory combinations, and improved power delivery capabilities. Such enhancements and improvements to methodologies and technologies may provide for increased tattoo artist productivity, enhanced tattoo-making abilities, and enhanced functionality.

SUMMARY

An adapter device for a tattoo machine and accompanying methods for utilizing the adapter device with a tattoo machine are disclosed. In particular, the adapter device enables a tattoo machine to switch from a fully wireless or other configuration to a wired configuration on the fly, such as by removing a wireless battery pack from the tattoo machine and replacing the wireless battery pack with the adapter described in the present disclosure. In certain embodiments, the adapter may be fitted with a connector, such as, but not limited to, a RCA connector that may couple with a power cable that may be utilized to deliver power to the tattoo machine when the tattoo machine is connected to the adapter and the coupled power cable is connected to a power supply supplying the power. The power supply may be any device may connect to a power source, such as a wall socket or other power source, and which may be utilized to deliver power to the tattoo machine via the adapter. For example, the power supply may be a traditional power supply device, a wired or wireless footswitch for controlling the tattoo machine, any other device for controlling the tattoo machine, a programmable power supply, a capacitive power supply, a direct current power supply, an AC-DC power supply, any other power supply, or a combination thereof. In certain embodiments, the adapter may include a female RCA connector attached on one end of the adapter, and, on the opposite end (or other desired location), the adapter may include a printed circuit board with custom designed plating that is configured to make contact with pins on a motor assembly of the tattoo machine so that power may be transferred to the tattoo machine via the adapter. An internal circuit of the printed circuit board may be configured to ensure that the power delivered to the motor of the tattoo machine via the power cable attached to the female RCA connector always has the correct polarity regardless of the input polarity.

In one embodiment, a machine including a tattoo machine portion and an adapter is provided. The tattoo machine portion of the machine may include a receptacle for receiving and connecting to the adapter, and a motor for power and enabling the tattoo machine to operate. In certain embodiments, the adapter may include a first portion configured to connect to the receptacle of the tattoo machine portion, and a second portion including a connector to connect to a power cable for delivering power to the motor of the tattoo machine portion when the first portion of the adapter is connected to the receptacle of the tattoo machine portion. In order to connect the first portion of the adapter to the receptacle of the tattoo machine portion, the first portion may include one or more extruded features that may be inserted axially into the receptacle of the tattoo machine portion. Once inserted, the first portion of the adapter (and the adapter itself) may be twisted in a direction (e.g. clockwise) until at least one of the extruded features contacts a ledge of the receptacle of the tattoo machine portion. When the at least one of the extruded features contacts the ledge of the receptacle of the tattoo machine portion, an o-ring (or other similar component) assembled to the adapter may be squeezed between the adapter and a body of the tattoo machine portion, thereby generating a pulling force on the plurality of extruded features and locking the adapter in place with the receptacle of the tattoo machine portion. When the adapter is locked into place with the receptacle, custom-designed plating of a printed circuit board of the adapter may contact pins of the motor of the tattoo machine portion to facilitate the transfer of power from the adapter to the motor. The end of the power cable not connected to the connector of the adapter may be connected to a power supply and power may be delivered to the tattoo machine via the adapter. Notably, the printed circuit board may include an internal circuit that ensures that the power delivered to the motor from the adapter has the correct polarity regardless of the input polarity.

In another embodiment, a method for utilizing an adapter with a tattoo machine is disclosed. The method may initially and optionally include removing a wireless battery pack from the tattoo machine. The method may then include aligning a first portion of the adapter with a receptacle of the tattoo machine. Additionally, the method may include inserting the first portion of the adapter axially into the receptacle of the tattoo machine. The method may proceed to include twisting the adapter after the first portion of the adapter is inserted axially into the receptacle until at least one extruded feature of the first portion contacts a ledge of the receptacle of the tattoo machine. Furthermore, the method may include locking, after conducting the twisting, the adapter onto the receptacle of the tattoo machine. In certain embodiments, locking of the adapter onto the receptacle may be based on the at least one extruded feature of the first portion contacting the ledge which may cause an o-ring (or other suitable device) assembled to the adapter to get squeezed between the adapter and the receptacle, thereby generating a pulling force on the at least one extruded feature that causes the adapter to be locked into place with the receptacle. In certain embodiments, when the first portion of the adapter is locked into place with the tattoo machine, plating of a printed circuit board of the adapter may contact pins on a motor assembly of the tattoo machine to facilitate delivery of power to the tattoo machine via the adapter. The method may also include connecting a first end of a power cable to a connector of a second portion of the adapter. The method may also include connecting a second end of the power cable to a power supply for delivering power to the tattoo machine via the adapter. Moreover, the method may include delivering the power to the tattoo machine via the adapter while ensuring a correct polarity for the power is provided to the motor using an internal circuit of the printed circuit board.

According to yet another embodiment, an adapter for use with a tattoo machine is disclosed. The adapter may include a first portion configured to connect to a receptacle of the tattoo machine, and a second portion including a connector configured to connect to a power cable for delivering power to a motor of the tattoo machine when the first portion is connected to the receptacle of the tattoo machine portion. In certain embodiments, the first portion of the adapter may be connected to the receptacle based on at least one extruded feature of the first portion contacting a ledge of the receptacle which causes an o-ring (or other similar device) assembled to the adapter to get squeezed between the adapter and the receptacle, thereby generating a pulling force on the at least one extruded feature that causes the adapter to be connected to the receptacle. An internal circuit of a printed circuit board of the adapter may ensure that the power delivered to the motor has a correct polarity when the first portion is connected to the receptacle—irrespective of the input polarity.
